I've been running the 4090 and currently the 5090 for a while now but I was always kinda scared the cable might someday melt on me too, even though I got a proper cable from BeQuiet which belongs to my PSU and avoided using the octopus adapter. Always made sure the cable was properly seated. Finally took the plunge and got the WireView Pro II which arrived today, and it seemed to be a right call. Luckily I was able to correct the issue by reseating the cable on both ends 3 times and now it's happy and evenly distributed.
